2010 DODGE CARAVAN check engine light

vehicle can be used to start and operate the vehicle. The
system will shut the engine off in two seconds if an
invalid Key Fob is used to start the engine.
After turning the ignition switch to the ON position, the
Vehicle Security Light will turn on for three seconds for a
bulb check. If the light remains on after the bulb check, it
indicates that there is a problem with the electronics. In
addition, if the light begins to flash after the bulb check,
it indicates that someone used an invalid Key Fob to start
the engine. Either of these conditions will result in the
engine being shut off after two seconds.
If the Vehicle Security Light turns on during normal
vehicle operation (vehicle running for longer than 10 sec-
onds), it indicates that there is a fault in the electronics.
Should this occur, have the vehicle serviced as soon as
possible by an authorized dealer.CAUTION!
The Sentry KeyImmobilizer system is not compat-
ible with some after-market remote starting systems.
Use of these systems may result in vehicle starting
problems and loss of security protection.
All of the Key Fobs provided with your new vehicle have
been programmed to the vehicle electronics.
Replacement Keys
NOTE: Only Key Fobs that are programmed to the
vehicle electronics can be used to start and operate the
vehicle. Once a Key Fob is programmed to a vehicle, it
cannot be reprogrammed to any other vehicle.

lamps and/or turn signals will flash and Vehicle Security
Light will flash repeatedly and the horn will sound. For
an additional 15 minutes, only the headlights, park lamps
and/or turn signals and Vehicle Security Light will flash.
The engine will run only if a valid key is used to start the
vehicle.
Rearming Of The System
The Vehicle Security Alarm will rearm itself after the 15
additional minutes of headlights and Vehicle Security
Light flashing, if the Vehicle Security Alarm has not been
disabled. If the condition which initiated the alarm is still
present, the Vehicle Security Alarm will ignore that
condition and monitor the remaining doors and ignition.
Arming The System
Remove the key from the ignition switch and either press
a power door lock switch while the driver or passenger
door is open, or press the LOCK button on the Remote
Keyless Entry (RKE) transmitter. After all the doors arelocked and closed, the Vehicle Security Light in the
instrument cluster will flash rapidly to signal that the
Vehicle Security Alarm is arming. The Vehicle Security
Light in the instrument panel cluster will flash rapidly for
about 16 seconds to indicate that the alarm is being set.
After the alarm is set, the Vehicle Security Light will flash
at a slower rate to indicate that the Vehicle Security
Alarm is armed.
NOTE:
If the Vehicle Security Light stays on continu-
ously during vehicle operation, have the system checked
by your authorized dealer.
Disarm The System
Either press the UNLOCK button on the RKE transmitter
or insert a valid ignition key into the ignition switch.
NOTE:
•The driver’s door key cylinder and the liftgate button
on the RKE transmitter cannot arm or disarm the
Vehicle Security Alarm.

Airbag Warning Light
You will want to have the airbags ready to
inflate for your protection in a collision. While
the airbag system is designed to be mainte-
nance free, if any of the following occurs, have
an authorized dealer service the system immediately.
•The Airbag Warning Light does not come on for
approximately four to six seconds when the ignition
switch is first turned ON.
•The Airbag Warning Light remains on after the ap-
proximate four to six-second interval.
•The Airbag Warning Light comes on intermittently or
remains on while driving.
NOTE: If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant Restraint
Controller (ORC) may also be disabled. The airbags may
not be ready to inflate for your protection. Promptly
check the fuse block for blown fuses. Refer to the label located on the inside of the fuse block cover for the
proper airbag fuses. See your authorized dealer if the
fuse is good.
Event Data Recorder (EDR)
In the event of a collision, your vehicle is designed to
record up to five seconds of specific vehicle data param-
eters (see list below) in an event data recorder prior to the
moment of airbag deployment, or near deployment (if
applicable), and up to a quarter second of either high-
speed deceleration data or change in velocity during
and/or after airbag deployment or near-deployment.
EDR data is ONLY recorded if an airbag deploys, or
nearly deploys, and is otherwise unavailable.
NOTE:
1. A near-deployment event occurs when the airbag
sensor detects severe vehicle deceleration usually indica-
tive of a crash, but not severe enough to warrant airbag
deployment.

Periodic Safety Checks You Should Make Outside
the Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread. Inspect the tread and sidewall for
cuts and cracks. Check the wheel nuts for tightness.
Check the tires (including spare) for proper pressure.
Lights
Have someone observe the operation of exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Door Latches
Check for positive closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid, or
brake fluid leaks are suspected, the cause should be
located and corrected immediately.

WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer if
your vehicle overheats. If you decide to look under
the hood yourself, see “Maintaining Your Vehicle”.
Follow the warnings under the Cooling System Pres-
sure Cap paragraph.
4. Speedometer
Indicates vehicle speed.
5. Turn Signal Indicators The arrow will flash with the exterior turn signal
when the turn signal lever is operated.
If the vehicle electronics sense that the vehicle has
traveled about 1 mile (1.6 km) with the turn signals on, a continuous chime will sound to alert you to turn the
signals off. If either indicator flashes at a rapid rate, check
for a defective outside light bulb.
6. High Beam Indicator
This indicator shows that the high beam head-
lights are on. Push the multifunction lever forward
to switch the headlights to high beam and pull toward
yourself (normal position) to return to low beam.
7. Anti-Lock Brake (ABS) Light This light monitors the Anti-Lock Brake System
(ABS). The light will turn on when the ignition
switch is turned to the ON position and may
stay on for as long as four seconds.
If the ABS light remains on or turns on while driving, it
indicates that the Anti-Lock portion of the brake system
is not functioning and that service is required. However,
the conventional brake system will continue to operate
normally if the BRAKE warning light is not on.

WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have failed.
It will take longer to stop the vehicle. You could have
an accident. Have the vehicle checked immediately.
Vehicles equipped with the Anti-Lock Brake System
(ABS), are also equipped with Electronic Brake Force
Distribution (EBD). In the event of an EBD failure, the
Brake Warning Light will turn on along with the ABS
Light. Immediate repair to the ABS system is required.
Operation of the Brake Warning Light can be checked by
turning the ignition switch from the OFF position to the
ON position. The light should illuminate for approxi-
mately two seconds. The light should then turn off unless
the parking brake is applied or a brake fault is detected.
If the light does not illuminate, have the light inspected
by an authorized dealer. The light also will turn on when the parking brake is
applied with the ignition switch in the ON position.
NOTE:
This light shows only that the parking brake is
applied. It does not show the degree of brake application.
9. Tachometer — Premium Instrument Cluster Only
The white area of the scale shows the permissible engine
revolutions-per-minute (RPM x 1000) for each gear range.
Before reaching the red area, ease up on the accelerator to
prevent engine damage.
10. Shift Lever Indicator
The Shift Lever Indicator is self-contained within the
instrument cluster. It displays the gear position of the
automatic transmission.
NOTE: You must apply the brakes before shifting from
PARK.

14. Electronic Stability Program (ESP) Indicator
Light / Traction Control System (TCS) Indicator LightIf this indicator light flashes during accelera-
tion, apply as little throttle as possible. While
driving, ease up on the accelerator. Adapt your
speed and driving to the prevailing road con-
ditions, and do not switch off the Electronic Stability
Program (ESP), or Traction Control System (TCS).
15. Malfunction Indicator Light (MIL) The Malfunction Indicator Light (MIL) is part of
an onboard diagnostic system called OBD that
monitors engine and automatic transmission con-
trol systems. The light will illuminate when the key is in
the ON position before engine start. If the bulb does not
come on when turning the key from OFF to ON, have the
condition checked promptly. Certain conditions such as a loose or missing gas cap,
poor fuel quality, etc., may illuminate the MIL after
engine start. The vehicle should be serviced if the light
stays on through several of your typical driving cycles. In
most situations, the vehicle will drive normally and will
not require towing.
CAUTION!
Prolonged driving with the MIL on could cause
damage to the engine control system. It also could
affect fuel economy and drivability. If the MIL is
flashing, severe catalytic converter damage and
power loss will soon occur. Immediate service is
required.

WARNING!
A malfunctioning catalytic converter, as referenced
above, can reach higher temperatures than in normal
operating conditions. This can cause a fire if you
drive slowly or park over flammable substances such
as dry plants or wood or cardboard, etc. This could
result in death or serious injury to the driver, occu-
pants or others.
16. Engine Temperature Warning Light This light warns of an overheated engine condi-
tion. As temperatures rise and the gauge ap-
proaches H,this indicator will illuminate and a
single chime will sound after reaching a set threshold.
Further overheating will cause the temperature gauge to
pass H,the indicator will continuously flash and a
continuous chime will occur until the engine is allowed
to cool. If the light turns on while driving, safely pull over and
stop the vehicle. If the A/C system is on, turn it off. Also,
shift the transmission into NEUTRAL and idle the ve-
hicle. If the temperature reading does not return to
normal, turn the engine off immediately and call for
service. Refer to “If Your Engine Overheats” in “What To
Do In Emergencies” for further information.
17. Electronic Throttle Control (ETC) Light
This light informs you of a problem with the
Electronic Throttle Control (ETC) system. The
light will come on when the ignition is first
turned ON and remain on briefly as a bulb
check. If the light does not come on during starting, have
the system checked by an authorized dealer.
If a problem is detected, the light will come on while the
engine is running. Cycle the ignition key when the
vehicle has completely stopped and the shift lever is
placed in the PARK position, the light should turn off.
